While the bilateral relationship has been turbulent for decades, the Trump presidency has damaged the Canada-US PSC by (1) exacerbating a decades-long trend of weakened shared identity and mutual trust between Canadians and Americans, and (2) undermining the democratic norms and institutions that uphold American domestic stability and Canadians’ expectations of peaceful change. Assessing the combined implications of the decline in shared identity, mutual trust and democratic stability, I argue that the Canada-US PSC cannot endure if the United States does not also consider Canada’s national and security interests or if the United States itself poses a threat to those interests. Given current trends, the future absence of war in North America may reflect American domination over a weaker and dependent Canada rather than their continued membership in a bilateral PSC. Résumé Cet article examine les relations canado-américaines à travers leur appartenance à une communauté pluraliste de la securité (CPS). Alors que les relations bilatérales ont été mouvementées pendant des décennies, la présidence Trump a porté préjudice à la CPS Canada-États-Unis 1) en exacerbant une tendance à l’affaiblissement de l’identité commune et de la confiance mutuelle entre Canadiens et Américains qui dure depuis des décennies, et 2) en sapant les normes et institutions démocratiques qui soutiennent la stabilité intérieure américaine et les attentes des Canadiens en matière de changement pacifique.
